– Convergence of health and economics.

Role in Syst-OMICS

With Yann Joly, I’m codirecting Activity 5 which aims to Identify and address the ethical, legal and economic concerns that may arise from a shift to a risk-based food safety approach to regulate Salmonella, based on the pathogenicity of individual bacterial isolates. My team is directly involved in assessing the economic factors that may influence the adoption of this new approach, particularly to:

• Assess the requirements for a risk-based approach to food safety in Canada;
  • Assess international trade impacts;
  • Evaluate the economic impacts of using a novel genomic test for Salmonella as compared to existing technology (costs & benefits, direct and indirect impacts);
  • Evaluate the public health costs and benefits of the new technology;
  • Evaluate the labour productivity impacts of increased food safety.

Florence Doualla-Bell obtained her PhD at the University of Paris-Sud (University of Paris XI) in France. After 18 years as associate professor in the Department of Medicine at McGill, she joined the Public Health Laboratory for the province of Quebec as Scientific Coordinator. She puts her skills and professional know-how at the service of health community in order to build research capacity and to develop appropriate research programs. Her ability to translate a concept into a measurable project, to manage diverse research projects simultaneously, to utilize team’s talent working always in a result oriented perspective define her work.

Role in Syst-OMICS

I am providing management and scientific supports to the project through the progress of Activity 4 research which aims to demonstrate the innovative use of next generation sequencing and efficient algorithm in developing guidelines for strain typing relevant for human surveillance and outbreak investigations. Indeed, I am responsible to ensure Activity 4 is completed on time and within the dedicated budget providing quarterly scientific and financial reports as requested. I also assist, participate and support student and staff in their scientific production.

With training in Food Science from University of Guelph (MSc & PhD), I initially worked as a Food Microbiology Professor at University of Wyoming and Colorado State University. Between 2013 and 2018, I was an Associate Professor and the Ian and Jayne Munro Chair in Food Safety, in the Department of Food Science and Agricultural Chemistry at McGill University. Since 2019, I’m a Leung Family Professor in Food Safety at the Canadian Research Institute for Food Safety, Department of Food Science, University of Guelph.

My primary research interests include the use of bacteriophages to control the growth of foodborne pathogens, and in development of rapid tests to detect foodborne and waterborne pathogens with an emphasis on Escherichia coli O157:H7, Salmonella spp, and Listeria monocytogenes, foodborne viruses. I’m developing novel molecular methods and I’m also looking at ways to mitigate bacterial contamination.

Role in Syst-OMICS

As the Project Leader, I’m responsible that the project will achieve its objectives and deliverables in compliance with the end-users and co-funders’ requirements. As a member of the Steering committee, I will follow the scientific progress of the project and make sure inter-activity synergy and coordination is happening. Finally, as a member of the Executive committee, I will oversee the general progress of the project and will also make decisions on issues whom may happened.

I am in charge of Activity 3 which aims at 1) improve the specificity of already existing commercially available immunoassays and RT-PCR assays; and 2) develop a new sequence-based molecular assay (AmpliSeq) capable of determining the pathogenic status of Salmonella isolates.

I am also involved in Activity 4.

Trained as a microbiologist at the University of Victoria, I’m the Section Manager of Microbiology Research at the Canadian Food Inspection Agency-Dartmouth Laboratory in Nova Scotia.

Over the last decade, my research is focused on studying, at the physiological and molecular levels, the relationships that exist between virulence (a measure of a pathogen’s ability to cause disease) and fitness (a measure of a pathogen’s ability to survive and grow in different environments) in foodborne and waterborne bacterial pathogens.  An understanding of these relationships would help us in controlling the spread of infectious diseases.

Role in Syst-OMICS

With my colleague John Rohde, I’m in charge of Activity 1.4.2 of the project, which aims at developing a high-throughput method to assess the virulence of selected Salmonella strains in two protozoan models: ciliates and amoebae.

It is reasonable to hypothesize that bacterial virulence factors used by contemporary human pathogens (like Salmonella) first evolved in the context of continuous bacterial interactions with bacteria-eating microbes (amoeba and ciliated protozoa), before animal forms of life emerged.  These factors must still play an important role in the survival and persistence of foodborne pathogens outside the human host, providing an excellent example of virulence-fitness relationships.  Besides highlighting potential (and arguably important) differences between environmental and clinical isolates of Salmonella, the presence or absence of genes associated with survival in protozoa could also be exploited both in the development of novel (albeit unconventional) Salmonella enrichment protocols required for its isolation in diagnostic testing, as well as in risk characterization of Salmonella isolates.

I’m a Lawyer Emeritus of the Quebec Bar since 2012 and also have a D.C.L. in Civil law from McGill University.

I’m also the Research Director of the Centre of Genomics and Policy, McGill University.

My research interests lie at the interface of the fields of intellectual property, health law (biotechnology and other emerging health technologies) and bioethics.

Role in Syst-OMICS

I am in charge of Activity 5 which aims to Identify and address the ethical, legal and economic concerns that may arise from a shift to a risk-based food safety approach to regulate Salmonella, based on the pathogenicity of individual bacterial isolates. My team is directly involved in assessing the legal and ethical factors that may influence the adoption of this new approach, particularly to:

• Identify the evidentiary requirements to support the change to a risk-based approach to food safety under Canadian and international law and policies;
• Identify legal and regulatory requirements for the approval of the new test;
• Identify policy drivers and potential hurdles to the uptake and broad use of the new test;
• Validate and disseminate GE³LS research results.

I favor an integrative approach (combining data from genomics, proteomics, and structural biology) to understand the interactions between phages and bacteria.

Role in Syst-OMICS

In Activity 2, I am involved in all sub-activities but my main contribution will be in the isolation and selection of isolates or mixtures of bacteriophages that will inhibit Salmonella In vitro and in planta.

My research interests are in the production and modification of biofilm-relevant polysaccharides by bacteria. Through my diverse research experiences, I have developed a multidisciplinary approach to tackling relevant research problems by employing biochemical, structural, microbiological and molecular biological techniques.

Role in Syst-OMICS

My role in the project is to profile the biofilm-forming capabilities of Salmonella isolates. Briefly, this encompasses exploring the importance of specific environmental factors that contribute to biofilm production of selected serovars. These results, combined with genetic information, will aim to determine relevant phenotypic groupings (e.g., curli/fimbriae, exopolysaccharides and other biochemical characteristics involved in biofilm production) related to adhesion and persistence on plant tissue surfaces. It is important to understand these phenotypic traits as many of these characteristics are associated with the surface receptors that bacteriophages use to target specific Salmonella serovars.
